[gotcha] Exposing sensitive actions as model-controlled tools instead of user-controlled resources

Map read-only or highly sensitive operations to MCP Resources \(application-controlled\) rather than MCP Tools \(model-controlled\). Require explicit user approval for state-changing tools.

Journey Context:
Developers often expose everything as a Tool because it's easy for the agent to call. However, Tools grant the LLM autonomy. If a sensitive operation \(like reading a database or deleting a file\) is a Tool, the agent can be tricked into calling it via prompt injection. Resources require the application/user to explicitly request them, providing a human-in-the-loop checkpoint.
